If you try HyperSPARC, please test without and with SMP.
Do you expect it to work at all, even UP? :-)
I'm asking because it used to be considered a lost cause but I did not
follow development recently.
Last time I have tried (and if I remember ;-) ), I have tested with
4*RT626. Kernel boots but randomly hangs due to a bug in cache aliasing
(I think). I don't remember if I have tried in UP configuration. I think
we have to try (and maybe to fix) last kernel because there is no modern
OS that runs on SS20/SMP/HyperSPARC :
- NetBSD 3.1 and 4.0 randomly crash with NMI error (and it's not an
hardware trouble because all my SS20/SMP/HyperSPARC crash with the same
error). It only supports SX fb in native resolution (not r1280x1024x66m);
- Solaris9 can not be used because it is impossible to run smpatch
without add sparcV8+ binaries (!), thus you have to keep a Solaris9 out
of the box... And I never obtain a stable SS20 with more than two
HyperSPARC's (with 3 or 4 RT626, I obtain the same NMI error than with
- Linux 2.2 is usable (but old). In SMP configuration, 2.4 is not stable
before 2.4.18 and randomly crashes with "Watchdog error" after 2.4.24.
If I have time to reinstall my Raid1 on one of my SS20, I shall try to
run 126.96.36.199 on HyperSPARC this afternoon.
